A container for separately accommodating a pair of liquids, such as mineral water and whisky, including a main body for accommodating a first liquid, a small cup for accommodating a second liquid, provided with a flange extending from the entire periphery of an upper end of the small cup and a skirt extending downward from the entire periphery of an upper end of the flange, and a flexible lid for liquid-tightly sealing an upper free opening of the small cup. The small cup is fit into an upper free opening of the main body engaging the flange and the skirt with the entire periphery of an upper end of the main body. The small cup has a specified area, in a bottom wall, at least partially bordered by a score line. The lid has a downward projection. The specified area is broken by pushing down the lid until a tip of the projection presses to break the specified area, whereby the second liquid flows down into the main body and mixes with the first liquid in the main body.
